waterproof ink

Rain-resistant writing fluid

Waterproof ink resists water damage after drying, maintaining legibility even when wet.

Used in fountain pens, technical drawing, and outdoor applications where documents might encounter moisture.

The ink typically contains shellac or other binding agents that become water-resistant once dry: Sign with waterproof ink so the rain doesn't smear your signature.
